it does for me

This does not.

Does it use color lines?

Well if you have a reference photo I may consider doing it, it just might take some time though.

I saw a new bus on the street earlier, Man A17, two door, and I was looking around on the workshop.

No, I would have to make it myself. But if you want one I could add it to my 'to do' list, if you wish for a particular livery i could do it as well.

So, the game just inverts the model if I use it in a right-hand world?

I mostly do left hand drive at the moment. But left hand drive and right hand drive vehicles are the same in this game as it's just a inversed version of the model. Pictures will be coming soon to all my models, however at the moment I am still in the process of touching them up and doing small refinements.

You Do all sorts of motors but cant see side view so dont know if left or right drive,
expecialy the busses, I am doing a left hand drive game but cant use any of your hard work,
please can you show side of motor or state if left Drive, cheers Keith
